Abstract

Variation in ozone transmittance with altitude in the atmosphere for radiation in the 9.6mm absorption band was studied using Goody model on the data comprising of pressure and temperature at different altitudes (0-26km) for three months (including January, February and March, 2019) in Lagos, southwest of Nigeria. Computed results showed that ozone transmittance increased with altitude, except for the altitudes 8km< Z≤ 12km and 16km< Z≤ 26km for January, 8km< Z ≤ 12km, 14km< Z ≤ 16km and 22km< Z ≤ 26km for February, and  8km< Z ≤ 10km and 14km< Z ≤ 26km for March, due to absorption of solar UV- radiation by ozone (O3) indicating that stratospheric ozone was effective in the study area preventing living things from being destroyed by this radiation.
